Unidentified vintage components
These components were in a box of vintage resistors. I don't know what they are and where they were used. Can anyone identify these please.

Re: Unidentified vintage components
Insulated stand offs and feed through ? used before tag strips the bush TR82 uses plastic items very similar.

Re: Unidentified vintage components
I have a couple of the bottom item, which is a feedthrough for bringing out a connection through a metal barrier or the wall of a metal box. It would be soldered in place. I don't recognise the other two.

Re: Unidentified vintage components
The top one is a simple stand-off tag connector - a single version of a tagstrip if you like. The spacer will be ceramic. The middle one looks very strange!

Re: Unidentified vintage components
Thanks gentlemen. That does make sense. First I thought they were old diodes but they are showing continuity on my meter apart from the ceramic glass 'waist' area.

Re: Unidentified vintage components
I also have some of these.
The lower item is probably made by KLG (of spark plug fame) and widely used in oil-filled transformers (Parmeko etc) where they are soldered into the sealed can to form the terminals. The middle one is of similar application but made of glass. |

Re: Unidentified vintage components
Feed through capacitors?

Re: Unidentified vintage components
Insulated feed thru's.
They also made feed thru capacitors that could look very close. Come to think of it, an insulated feed thru would have a certain amount of capacitance. |

Re: Unidentified vintage components
I seem to recall that the feed-through capacitors have a silver, or silvery, covering over the outside outer surface of the ceramic tube.
If so, as ukcol says, almost certainly 1000 P.F.. Tony |
